[DrDolittle]

what is the difference between relativistic and nonrelativistic equation. What is the difference in the meaning they convey ?

quantum robot is newly developing area.
I hope to get some inforamtion about it.
could you please tell me difference between newton dynamics and quantum dynamics?

Your questions cover a vast area of physics.
I think it's better to say that atoms are properly described only by quantum mechanics, classical mechanics (maxwell equations) fail to describe even atoms stability.
Classical mechanics opposite to relativistic mechanics:
the former consider space and time absolute and unrelated. Two people with different speed will measure the same lengths and time.
the latter consider the speed of light (c) as the only constant. The two people will measure the same c, but different lengths and times

Briefly, when the classical -Newtonian-mechanics failed to solve some sort of problems that arised in the begingings of the 19th century as the photoelectric effect and the description of the atom, this was attributed to that classical mechanics delt with particles that their velocities were so far of the spped of light(<<<c).
But inside the atom particles (electrons, protons....) move with velocities that are fractions of c.
as a result new revolutionary type of mechanics was developed by (Hisenberg-Einstein-Pauli... and many others.
